Iyengar Yoga was founded by B.K.S. Iyengar, one of the most influential and respected figures in modern yoga. Born into a modest family in Bellur, India, in 1918, Iyengar's early life was marked by serious childhood illnesses, including tuberculosis, malaria and typhoid. These physical challenges were the driving force behind his quest for healing, which he found through yoga under the tutelage of his brother-in-law, T. Krishnamacharya, at the age of 15. Krishnamacharya, considered the "father of modern yoga", had a decisive influence on the development of Iyengar's practice, and he went on to become a pioneer in the spread of yoga in the West.

B.K.S. Iyengar developed his own approach to yoga, focusing onprecise body alignment, rigorous technique and the use ofprops to help practitioners enter the postures, whatever their physical condition. The influence of anatomy and biomechanics is a central aspect of Iyengar Yoga, where each posture is meticulously broken down to ensure that the body is perfectly aligned. Unlike other yoga styles that focus on fluid movement or speed, Iyengar Yoga is distinguished by itsextreme attention to detail and in-depth exploration of each posture. Iyengar firmly believed that correct alignment in asana could heal the body, stabilize the mind, and pave the way for spiritual transformation.

Iyengar's approach is also deeply influenced by the teachings of Patanjali's Yoga Sutra, which he considered an essential source for understanding the essence of yoga. He attached particular importance to the concept of sthira-sukham asanam, the combination of stability (sthira) and comfort (sukha) in each posture. For Iyengar, a correctly aligned posture should not only be a physical position, but also an expression of the balance between strength, suppleness and inner tranquillity.

The introduction of props - blocks, straps, blankets, wall ropes and chairs - was a major Iyengar innovation that made yoga accessible to all, regardless of age or physical limitations. These accessories help practitioners to maintain postures with precision, while reducing the risk of injury. This methodical approach has also enabled many people with chronic physical problems or injuries to enjoy the benefits of yoga in a safe and appropriate way.

In 1966, B.K.S. Iyengar published his revolutionary "Light on Yoga", which quickly became a reference manual for yogis the world over. The book, often referred to as the "yoga bible", contains detailed descriptions and illustrations of over 200 postures, as well as instructions on pranayama techniques (breathing exercises) and the therapeutic benefits of yoga. Thanks to this work, Iyengar Yoga spread rapidly around the world, and yoga centers were opened in countries as diverse as the USA, England, Australia and France.

The therapeutic dimension of Iyengar Yoga is another fundamental aspect of this method. B.K.S. Iyengar believed that correctly aligned postures could rehabilitate injuries, improve blood circulation, and even treat certain chronic illnesses. He developed specific series for physical problems such as backache, joint disorders and muscular pain, making yoga accessible even to people in convalescence or with reduced mobility.

On a spiritual level, Iyengar Yoga is not just a physical practice, but a path todeep introspection and self-knowledge. By demanding intense concentration on every detail of the posture, this method engages the practitioner in developing total mental presence, cultivating inner stability and peace of mind. Iyengar believed that the perfect union of body and mind through asana could lead to spiritual transformation and a deeper connection with the divine.

Today, Iyengar Yoga is practiced worldwide, with thousands of certified teachers and dedicated centers in many countries. B.K.S. Iyengar's legacy lives on through his writings, teachings and the worldwide community of practitioners who perpetuate his rigorous method and commitment to the practice of yoga as an art and science of life.
